Simply provider versions in examples

[jeanduplessis]

Provider versions change constantly, and updating the examples in the docs with every release is not feasible.
Users of the docs sometimes end up installing very old versions of the providers, which results in a sub-optimal experience and the need for help.

This PR introduces two main changes:

1. The provider version to be installed is set to the major version only, e.g., v1 instead of v1.2.3. This has the effect of installing the latest provider version of the v1 major release. Note this capability is limited to the Upbound Marketplace for the providers used in the Quickstart guide.
2. Updates the example output where provider versions are listed all to v1.0.0 for consistency.

This looks like a nice experience update @jeanduplessis. A couple places to check if we could just use v1 instead. If you look at those and confirm with testing that v1 tag pulling works, then this looks good to me! 🙇‍♂️
